Question: When did person who supervised the design and implementation of the iPod user interface die?
Context: Document 1: Inside Out (2015 film): In late 2009, Docter noticed his pre-teen daughter, Elie, exhibiting similar shyness. "She started getting more quiet and reserved, and that, frankly, triggered a lot of my own insecurities and fears," he said. He imagined what happens in the human mind when emotions set in. The idea to depict it through animation excited Docter, who felt it the ideal form to portray "strong, opinionated, caricatured personalities". He began researching information about the mind, alongside Jonas Rivera, a producer, and Ronnie del Carmen, a secondary director. They consulted Paul Ekman, a well-known psychologist who studies emotions, and Dacher Keltner, a professor of psychology at the University of California, Berkeley. Ekman had early in his career identified six core emotions—anger, fear, sadness, disgust, joy, and surprise. Docter found surprise and fear to be too similar, which left him with five emotions to build characters around. Other emotions considered for inclusion during the development process were schadenfreude, ennui, pride, and hope. Keltner focused on sadness being an emotion that strengthens relationships. Both emphasized how emotions organize social lives and the structuring of interpersonal interactions.The smash success of Docter's 2009 film Up encouraged those at Pixar to allow Docter to create another film with a more sophisticated story. Inside Out is the first Pixar film without input from co-founder and former Apple CEO Steve Jobs, who died in 2011. In addition, the film did not have as much input from chief creative officer John Lasseter, who was focused on restructuring Walt Disney Animation Studios in Burbank at the time of its production. Executives at Disney and Pixar were positive at the proposal of making Inside Out, but acknowledged it would be difficult to market.
Document 2: IPod: Apple did not develop the iPod software entirely in-house, instead using PortalPlayer's reference platform based on two ARM cores. The platform had rudimentary software running on a commercial microkernel embedded operating system. PortalPlayer had previously been working on an IBM-branded MP3 player with Bluetooth headphones. Apple contracted another company, Pixo, to help design and implement the user interface under the direct supervision of Steve Jobs. As development progressed, Apple continued to refine the software's look and feel. Starting with the iPod Mini, the Chicago font was replaced with Espy Sans. Later iPods switched fonts again to Podium Sans—a font similar to Apple's corporate font, Myriad. iPods with color displays then adopted some Mac OS X themes like Aqua progress bars, and brushed metal meant to evoke a combination lock. In 2007, Apple modified the iPod interface again with the introduction of the sixth-generation iPod Classic and third-generation iPod Nano by changing the font to Helvetica and, in most cases, splitting the screen in half by displaying the menus on the left and album artwork, photos, or videos on the right (whichever was appropriate for the selected item).
